Title: Improvements in and relating to a pipe joint of the bell and spigot type
IPC: F16L21/08
Filed: 1950-08-03
Abstract: 692,159. Pipe joints. KONINKLIJKE NEDERLANDSCHE HOOGOVENS EN STAALFABRIEKEN, N. V. Aug. 3, 1950 [March 14, 1950], No. 19391/50. Class 99 (i). - In a pipe joint of the bell-and-socket type in which packing, such as a rubber ring 4, placed radially between the bell 1 and spigot end 2 is compressed by a pressure ring 5 that has lugs engaging corresponding lugs on the bell 1 so that it can be partially rotated to exert pressure on the packing 4, there is provided a locking ring 8, preferably incorporating a gap, which acts as a wedge and co-operates with a circumferential groove 10 of the spigot end and a diverging surface 9 of the pressure ring 5. Clearances 6 and 7 are provided between the bell 1 and spigot 2 to facilitate relative movement between the pipes, such movement being restricted by the ring 8; the latter may have a trapezoidal, elliptical or circular crosssection. The bottom surface of the groove may be inclined to, or parallel with, the longitudinal axis of the spigot. The surface 9 has the shape of a spherical segment, whilst the packing 4 seats against a conical portion 3 of the bell 1.

Title: Improvements in machines for charging and discharging gas retorts and the like
IPC: C10B35/00
Filed: 1924-08-16
Abstract: 242,369. Canning, T. F., and Clark, R. G. Aug. 16, 1924. Charging and discharging.-An apparatus for charging and discharging through or stop ended retorts comprises a jointed bar 3 around which runs an endless chain 5 carrying transverse pushers 6, the whole being wound on an operating wheel or drum 1. The bar 3 is attached at one end to an arm 7, which can be clutched when desired to the wheel 1, and which may carry a wheel or roller to facilitate the travel of the chain. Close to the feed shoot b the chain passes between a pair of sprockets 8, 9, of which the upper is idle while the lower can be driven through a dog clutch from the wheel 1. In operation the device is thrust into the retort to discharge the coke, and fresh fuel is simultaneously fed between the pushers from the shoot b. The clutch is now engaged to drive the sprocket 9 and the chain 5 runs round the bar 3 with the lower lap travelling into the retort so that fuel is carried forward and piled up in advance of the end of the chain. When the coal is sufficiently packed the clutch is brought to neutral, and the drive of the chain from the wheel 1 being continued the bar 3 is retracted, as the lower lap of the chain tend to remain stationary. If desired, during this part of the operation, a pin may be thrust into the lower lap of the chain, or a brake may be applied to the sprocket 9. When a sufficient return movement has been made the clutch is re-engaged and the chain alone driven to pile the charge up as before. These operations are repeated as often as may be necessary, and by varying the withdrawal movement in relation to the feed movement any desired degree of packing can be obtained. For discharging stop-ended retorts the device is inserted into the retort mouth and operated so that the lower lap of the chain runs outwards. The sprocket 9 is arranged to drive the chain at the same rate as the wheel 1, but by using different-sized sprockets the drive may be so arranged that the bar 3 is advanced or retarded while the chain is moving round it.

Title: A shaped elastomeric article and a method for the continuous manufacture thereof from shaped elastomeric material
IPC: B29C48/03
Filed: 1963-05-16
Abstract: Shaped elastomeric material is continuously manufactured by preparing a composition in which at least 50% of the total elastomeric content is a butadiene-styrene-divinylbenzene terpolymer, the composition including one or more fillers in a total amount of not less than 30 parts by weight per 100 parts by weight of the total elastomeric content; extruding the composition; and subjecting the shaped material, on emerging from the extruder, to continuous vulcanization in hot air.  Suitable additional elastomers for incorporating with the terpolymer include natural rubber, butadiene-styrene or butadiene-acrylonitrile copolymers, polybutadiene, polyisoprene and polychloroprene and may be used in their normal or "oil extended" forms.  The fillers may be any of the usual rubber fillers of which zinc oxide, aluminium silicate, carbon black and kaolin are exemplified.  The fillers are heat and/or vacuum treated, if necessary, to render them capable of absorbing the gases or vapours evolved during vulcanization.  Conventional rubber additives such as vulcanizing agents, accelerators, diluents and anti-ageing agents may be included in the composition.

Direct air-pressure apparatus, non-automatic; valves for liquid, arrangement of; valves for pressure fluid, arrangement and actuation of.-Pneumatic apparatus for raising or forcing liquids and semi-liquid such as heated bitumen comprises a vessel 1 submerged in the. liquid and provided with an inlet valve 5 and a delivery pipe 10 for the liquid. The stem 11 of the valve 5 is connected to the trunk 12 of a piston 13 in a cylinder 14. which is connected by ports 16, 17 and pipes 21, 30 to a valve 18 controlling the supply of compressed air &c. The piston 13 and trunk 12 are hollow and the trunk has perforations 15, so that when pressure fluid is admitted to the top of the piston by the port 16 to depress the piston and close the valve 5, it passes through the holes 15 into the vessel 1 and discharges the liquid. The pressure fluid passes to the port 16 when the passage 25 in the valve 18 is coaxial with the air supply port 19. When the valve 18 is turned to cut off the port 20 from the port 19 and connect it to a port 22 open to atmosphere or to the vessel 1, the pressure fluid passes by the port 27, pipe 30 and port 17 to the under side of the piston 13 and opens the valve 5 to allow a fresh supply of liquid to enter the vessel 1. When the valve 18 is turned so that the port 26 is open to the port 19, the air passes through a pipe 23 into the lower part of the vessel 1 to stir the liquid. The valve 5 and its stem are enclosed in a cage 2 which is inserted in the vessel 1 through an aperture in the top.

Title: Improvements in or relating to the manufacture of rubber compositions
IPC: C08L7/00
Filed: 1932-07-15
Abstract: Crumb like or granular compositions consisting of rubber and granular, fibrous or divided materials are prepared by admixing flocculent precipitates of rubber containing aluminium silicate produced in situ with such materials, the amount of precipitate and the quantity of water being so regulated as to result in products of a crumb-like character.  The granular, fibrous and divided materials include leather fibre, wood flour, cork dust, jute fibre, cotton flock, naturally short cellulose fibres and ground fibres.  Softening and adhesive agents may be incorporated in the composition.  The compositions so formed may be sheeted out as in the linoleum industry, together with, if desired, a fabric backing.  Decorative effects may be produced by using differently coloured crumbs or by painting the surface of the finished article with paint or cellulose colours.  The rubber dispersions include those of rubber, guttapercha, balata, coagulated rubber, vulcanized rubber, synthetic rubber, waste or reclaim, and may contain the usual compounding and vulcanizing ingredients.  The precipitates are prepared by coagulation in the presence of a relatively large amount of water, such, e.g. that the dispersion contains not more than 10 gms. total solids per 100 ccs.  In a detailed example, a flocculent precipitate containing rubber, sulphur, zinc oxide, accelerator aluminium silicate, and mineral oil precipitate containing mineral oil, sulphonated oil, and aluminium silicate, is admixed with cork dust, lithopone and iron oxide.  The crumb is dried and sheeted. Specifications 219,635, 290,313, [both in Class 70, Indiarubber &c.], 373,222, 373,263, and 396,159 are referred to.  The Provisional Specification describes also the use of flocculent precipitates of rubber in which coagulation has been effected by metallic salts produced in situ, acids such as acetic acid, salts such as zinc sulphate and magnesium sulphate and refers to substances having a restraining effect on the coagulation such as caustic potash, casein, sodium aluminate, glue and gum acacia.
